如何为oslog创建的日志添加不同的日志记录器(如文件和Crashlytics等输出目标)？

import os
import Crashlytics

// 创建文件日志记录器
let fileLogger = OSLog(subsystem: "com.example.app", category: "fileLogger")
let fileURL = URL(fileURLWithPath: "/path/to/log/file.log")
let fileHandle = try? FileHandle(forWritingTo: fileURL)
if let fileHandle = fileHandle {
    os_log("File logger initialized", log: fileLogger, type: .info, fileHandle: fileHandle)
}

// 创建Crashlytics日志记录器
let crashlyticsLogger = OSLog(subsystem: "com.example.app", category: "crashlyticsLogger")
Crashlytics.start(withAPIKey: "YOUR_API_KEY")
os_log("Crashlytics logger initialized", log: crashlyticsLogger, type: .info)

// 记录日志
os_log("This is a log message", log: fileLogger, type: .info)
os_log("This is another log message", log: crashlyticsLogger, type: .info)
